Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00059 | $0.00623 |
| Opus 5 | $0.00030 | $0.00311 |
| Sonnet 5 | $0.00012 | $0.00125 |
| Haiku 4.5 | $0.00006 | $0.00062 |
Grade A, and why
ta-datev-preparation scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Help the tax advisor prepare and execute a DATEV export:
Step 1: Verify DATEV settings
- Call
get_company_detailsto check current DATEV configuration - Verify the following are set:
- Chart of accounts (SKR03 or SKR04)
- DATEV advisor number (Beraternummer)
- DATEV client number (Mandantennummer)
- If any are missing, inform the advisor and offer to update via
update_company_details
Step 2: Check categorization completeness
- Call
search_transactionswithstatus=UNVERIFIEDto find uncategorized transactions - Report the count and total amount of uncategorized transactions
- If there are uncategorized transactions:
- List the top items by amount
- Offer to help categorize them using company categories (
list_company_categories) - Warn that uncategorized transactions will be exported without a DATEV booking account
Step 3: Check receipt completeness
- Call
get_missing_documents_summaryto identify transactions without receipts - Focus on expense transactions >250 EUR (required for Vorsteuerabzug)
- Report the count and recommend collecting missing receipts before export
Step 4: Pre-export summary
DATEV Configuration
- Chart of accounts: SKR03/SKR04
- Advisor number: ✅/❌
- Client number: ✅/❌
Data Completeness
- Total transactions in period: X
- Categorized: X (Y%)
- With receipts: X (Y%)
- Ready for export: X (Y%)
Issues to Resolve
List any blocking issues before export
Step 5: Trigger export
- Only proceed if the advisor confirms
- Call
trigger_datev_exportto generate the DATEV EXTF CSV package - The export includes:
- DATEV EXTF CSV file (booking records)
- Transaction statement
- Attached documents
- Provide the download link from the response
Step 6: Post-export
- Confirm the export was successful
- Remind the advisor to import the file into their DATEV software
- Suggest marking the period as exported to avoid duplicate exports
Tips:
- DATEV EXTF format is the standard for German tax advisors
- SKR03 is the most common chart of accounts; SKR04 is used by some industries
- Always verify advisor and client numbers match the DATEV installation
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
